HVAC TUNE UP AND MAINTENANCE CHECK
Portland and Bend, Oregon

What does the tune up and maintenance check include?

When you sign up for the Home Performance Plan, you get biannual HVAC tune ups and maintenance checks. Here you’ll find an overview of the services completed during the tune up and check. If you have questions, please give us a call in Portland (503.223.8767) or Central Oregon (541.330.8767).

Overall HVAC Service Priorities

• CONTROLS AND SAFETIES: Inspected and tested. Controls and safeties that do not function properly can increase operation cost and cause other components to fail.

• MOTORS: Cleaned and inspected. Dirty motors are less efficient and will fail sooner.

• LUBRICATION: Applied to motors and bearings. Improperly lubricated rotating equipment will eventually fail.

• BELTS AND PULLEYS: Inspected and adjusted. Loose belts and worn pulleys decrease air flow, increase operating costs and shorten the compressor’s life. Belts can crack and break with age.

• VOLTAGE AND AMP: Draw of the blower motor, compressor and condenser fan motors checked and recorded. Improper voltage and amp draw increase operating costs and can shorten the life of any motor.

• TEMPERATURES AND PRESSURES: Recorded. An accurate record of vital data can indicate potential problems that can be eliminated.

• PANELS: All panels secure. Loose panels can increase operating costs and cause either a shutdown or a dangerous condition.

• AIR FILTER: Replaced with client approval and at least 24-hours advance notice of filter dimensions. Pricing includes a standard 4” MERV 8 filter; more expensive filters incur an additional charge.

gas FURNACE SERVICE

• HEAT EXCHANGER: Inspected for cracks and deterioration. Heat exchangers can develop cracks with age. If they exist, there is a risk of serious illness or an explosion from leaked carbon monoxide.

• BURNERS: Removed and cleaned if necessary. Dirty burners can cause poor combustion, soot, and condensation, which will shorten the life of the furnace.

• FAN SWITCH: Checked and adjusted. A fan switch that is not properly adjusted can waste energy and cause nuisance fan cycling.

• PILOT AND PILOT ASSEMBLY: Cleaned and adjusted as necessary. Weak or dirty pilots can be easily extinguished, causing the furnace to shut down.

• GAS LINE: Checked for leaks between the furnace shut off valve and the burners. Undetected gas leaks can result in a buildup of carbon monoxide, increasing the risk of sickness or an explosion in the home.

• COMBUSTION AIR: Openings checked. Blocked or restricted combustion air openings can be dangerous.

• FLUE PIPE: Inspected. Flue pipe corrosion or leaks are dangerous.

AIR CONDITIONER / HEAT PUMP MAINTENANCE

• CONDENSER COIL: Cleaned as required. Dirty condenser coils raise refrigerant pressure higher than needed, increasing your electric bill.

• REFRIGERANT CHARGE: Checked by superheat / subcooling method. A low or high refrigerant charge can easily go unnoticed and increase operating costs up to 30%. An improper charge can cause compressor shutdown.

• RELAYS AND CONTACTS: Inspected and cleaned. Worn contacts and loose wire connections can lead to motor or compressor failure.

• CRANKCASE HEATER: Operationally inspected. Crankcase heaters that do not work can lead to a compressor failure.

• UNIT WIRING: Inspected and loose connections tightened. Loose connections can lead to a motor, control, or compressor failure.

• CAPACITORS: Tested. Bad capacitors can lead to compressor and motor failure.

• UNIT DISCONNECT: Tested. A worn or over-heated disconnect blows fuses and is dangerous.

• CONDENSATE DRAIN: Checked to ensure it is open. Algae and dust can plug a condensate drain which can cause extensive water damage to your furnace.
